Accessing a 100k of files (filenames to be exact) in a UTF-8 environment (Linux), which must all be stored in a UTF-16 string type. That's lots and lots of encoding conversions right there - in a tight loop.
It's nevertheless a bad example, because even with the fastest SSD all those conversions will probably be hidden by I/O and memory latency. Even if you would implement something like the Unix "find" or "ls" programs, they would be more likely to be limited by I/O and all sorts of file/directory attribute lookups than code page conversions of file names.
